What tests can be done to diagnose angina?

Under normal circumstances, angina pectoris can be diagnosed through tests such as ambulatory electrocardiography (Holter monitoring), electrocardiographic stress testing, stress imaging, echocardiography, and coronary angiography. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment. Specific analyses are as follows:

1. Ambulatory Electrocardiography (Holter Monitoring)

By continuously recording electrocardiographic changes over 24 hours or longer, this test helps determine the frequency of angina episodes and identify the location of myocardial ischemia, thereby clarifying the specific condition.

2. Electrocardiographic Stress Testing

Performed under the supervision of trained medical professionals, this test monitors for signs of myocardial ischemia during increased oxygen demand, helping to confirm the presence of angina pectoris.

3. Stress Imaging

Conducted by qualified physicians, stress imaging allows direct visualization of myocardial blood supply areas and helps assess the severity of angina.

4. Echocardiography

Echocardiography is primarily used to evaluate cardiac function and can detect various types of heart diseases, including angina. Stress echocardiography further aids in assessing the extent of myocardial ischemia.

5. Coronary Angiography

As an invasive procedure, coronary angiography enables direct visualization of the degree and location of coronary artery stenosis, providing a highly accurate diagnosis of angina pectoris.

Maintaining healthy lifestyle habits is essential. Avoid excessive fatigue and strenuous exercise to prevent physical discomfort. It is advisable to engage in moderate activities such as walking or jogging according to individual capacity, which can enhance physical immunity and support recovery.
